From the publisher's description:
SECRETS OF SAN FRANCISCO provides excellent background for a Call of Cthulhu campaign set in the Bay Area of the 1920s. It includes urban geography, civic history and research venues, and mythos lore. Many period photographs are provided and dozens of historical figures are introduced, including several who collaborated and corresponded with Lovecraft. Here are provided descriptions of where San Franciscan’s are sent when they break the law, go insane, or pass-beyond. Here are the sights, sounds, and secrets of this place that makes it a unique city.
